Steps needed to patch update.upt with rockbox bootloader are explained in
bootloader_install.sh shell script. Process is quite involved and some
custom tools are needed.
For convenience Dockerfile is provided which prepares custom image based
on debian 9 which has all the tools needed to work with Agptek Rocker update
images.
Basically image extends standard debian image by:
1) Installing developer packages from stock debian
2) Cloning https://github.com/wodz/rockbox-wodz.git
3) Building custom cross toolchain
4) Cloning and installing tools to work with UBIFS
You first need to build image with:
docker build . -t "agptek-dev"
Then you can start container and work with update.upt.
If you want to generate patched update image in automatic way:
docker run --rm -it -v /path/to/dir/with/update.upt:/upt \
-e UPT_DIR=/upt agptek-dev bootloader_install.sh
Patched update.upt with rockbox bootloader and rockbox.zip should end up in
specified directory.
If you want to play around, hack something etc. you can run container in
interactive mode:
docker run -it -v /path/to/dir/with/update.upt:/upt \
-e UPT_DIR=/upt agptek-dev bash
